The Microsoft JVM Removal Tool can be used to remove the MS Java Virtual Machine (MSJVM).Use of this tool is the only supported method for removing the MSJVM from a Microsoft operating system.

If you use the MSJVM Removal Tool, Microsoft will not be able to provide you with a copy of the MSJVM if you decide you want to reinstall the MSJVM later. Your only options for reinstallation of the MSJVM will be to install from a prior image that includes the MSJVM, reinstall a third party application that includes the MSJVM, or reinstall the applicable Windows Operating System from media. If you no longer have the media for a Windows Operating System that includes the MSJVM, you may not be able to get such media from Microsoft. If you use the MSJVM Removal Tool you agree that Microsoft has no obligation to provide you with the MSJVM.

Usage Notes

- Users should carefully assess their MSJVM dependencies before running this tool. Users should consult http://go.microsoft.com/fwlink/?LinkID=21850in order to understand MSJVM issues and get the latest available information about MSJVM removal. Third party applications may continue to have MSJVM specific dependencies for an unknown amount of time and users may depend on these applications. Therefore, Microsoft highly recommends that this tool be run in a test environment prior to removing the MSJVM on production or critical systems.

- You must be logged on as an administrator to use this tool.

- You may run or deploy this tool with user interface or with the scriptable command line interface. Command line options are the same as the options for IExpress packages.Information on command line switches can be found at http://go.microsoft.com/fwlink/?LinkID=9187.

- On operating systems that do not have system file protection, MSJVM files and associated registry keys will be removed completely.

- On operating systems where the MSJVM files are under system file protection (windows 2000 SP2, Windows 2000 SP3, and Windows Millennium), all MSJVM files will be replaced with 1-byte files with a higher version number. Once the tool is run on these systems, the MSJVM will never be able to be re-installed.
